A ZUGFeRD xml generator and validator

More info coming soon. See tests for examples.

Some words of caution

1. This is an opinionated library optimised for my very specific usecase
2. While I did start to add some validations to make sure you can't input absolute garbage into this, I cannot guarantee factual (as in taxation law) correctness of the resulting XML.
3. This does not contain any code to attach the XML to a PDF file, mainly because I have yet to find a ruby library to do that.
